gdp平减指数计算方法

gdp平减指数计算方法GDP可以分为现价GDP与不变价GDP,真实GDP等于现价GDP除以GDP平减指数，然而在统计年鉴中，并没有直接给出GDP平减指数以及计算方法下面我们对GDP平减指数的计算方法作以简要介绍GDP平减指数等于现价GDP除以不变价GDP，若1978年的指数为100,1979年的GDP指数为107.6,是指与1978年相比，按可比价计算GDP增加了7.6%,1978年的GDP为3624.1,则按不变价计算,1979年的GDP等于3624.1乘以107.6等于3899.53,则1979年的平减指数为现价(1979)4038.2/3264.1=103.56据此计算，则GDP平减指数及真实GDP如下表：年份现价GDP1978=100的指数不变价GDP平减指数真实GDP19783624.10100.003624.10100.003624.1019794038.20107.603899.53103.563899.5319804517.80116.004203.96107.474203.9619814862.40122.104425.03109.884425.0319825294.70133.104823.68109.764823.6819835934.50147.605349.17110.945349.1719847171.00170.006160.97116.396160.9719858964.40192.906990.89128.236990.89198610202.20210.007610.61134.057610.61198711962.50234.308491.27140.888491.27
